Questions and Answers
  • 1. 

    Tick all the TRUE statements

    • A.

      The moon does not emit light

    • B.

      The sun reflects light

    • C.

      Stars emit light

    • D.

      Humans do not emit visible light

    Correct Answer(s)
    A. The moon does not emit light
    C. Stars emit light
    Explanation
    'Emit' means put out or produce light

    Rate this question:

  • 2. 

    Which one describes WAVELENGTH?

    • A.

      The distance a light ray travels each second

    • B.

      The distance between the crest of a wave and the trough (lowest point)

    • C.

      The distance between Earth and the sun

    • D.

      The distance between two crests right next to each other in a wave

    Correct Answer
    D. The distance between two crests right next to each other in a wave
    Explanation
    The correct answer is "the distance between two crests right next to each other in a wave." This is because wavelength refers to the distance between two consecutive crests or troughs in a wave. It is a measure of the spatial extent of one complete cycle of a wave and is commonly represented by the symbol λ (lambda).

    Rate this question:

  • 3. 

    Which is the definition of light?

    • A.

      The movement of air particles hitting your eardrum

    • B.

      A force that all objects with mass have

    • C.

      A type of energy (electromagnetic) that we can detect with our retina

    • D.

      What all matter is made up of

    Correct Answer
    C. A type of energy (electromagnetic) that we can detect with our retina
    Explanation
    Light is defined as a type of energy (electromagnetic) that we can detect with our retina. This definition accurately describes light as a form of energy that is visible to us through our sense of sight. Light is a fundamental part of the electromagnetic spectrum and is characterized by its ability to travel in waves and particles called photons. When light enters our eyes, it stimulates the cells in our retina, allowing us to perceive it as different colors and brightness levels.

    Rate this question:

  • 4. 

    Humans can see all wavelengths of light

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    NO: visible light is a very small part of the electromagnetic spectrum (possible wavelengths)

    Rate this question:

  • 5. 

    Which is TRUE?

    • A.

      Light with a shorter wavelength has MORE energy than longer wavelengths

    • B.

      Light with a shorter wavelength has LESS energy than longer wavelengths

    Correct Answer
    A. Light with a shorter wavelength has MORE energy than longer wavelengths
    Explanation
    Because it takes more energy for the photon to move up and down more often (shorter wavelength/greater frequency)

    Rate this question:

  • 6. 

    The colours of the rainbow are red, orange, yellow, green, blue, ___________ and violet.

    Correct Answer
